Market context
The Strait of Hormuz has been effectively closed for 100 days due to escalating conflict between Iran and the United States, halting a route that once carried 20% of global oil and natural gas supplies[2][4]. Commercial shipping remains suspended after a brief reopening, with Iran employing asymmetric power via drones and missiles to maintain control while keeping oil prices elevated[2]. The closure has triggered a massive spike in freight rates, with carriers imposing surcharges of $1,500 per shipment to the Persian Gulf, while the estimated daily economic cost exceeds $4 billion[1][3].
Historical precedents for such a systemic, non-cyclical shock in modern history suggest that a return to 60 daily transit calls by July 7 is highly improbable given the current 8% market-implied probability[2]. While verified crossings reached 25 on 18 June, marking a notable increase from near-standstill levels, this figure remains less than half the threshold required for a "Yes" resolution[6][8]. Previous attempts to reopen the waterway failed quickly after Iran reversed its decision following reported attacks, indicating that sustained traffic recovery is unlikely without a formal ceasefire[10].
Traders must monitor President Trump’s stipulation that reopening the strait is a prerequisite for any ceasefire agreement with Tehran, as minimal progress in peace negotiations has led to a declared naval blockade[4]. Key dependencies include the expiration of war risk cover and the threat of missile attacks, which continue to deter tanker owners despite some vessels attempting transits without AIS[1][5]. Any announcement regarding the removal of mines, which Tehran has implied were laid in the strait, or a shift in US-Israeli attack patterns following the February 28 assault, would be critical catalysts for traffic recovery[4].

FAQ
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
